Last night I gave my new FF a run on the ED80. Worked beautifuly. I have to tweak the spacing but I got a very significant improvement on the original field. The night was very good. Dry no wind and good seeing so I left the scope pointing south and kept shooting.
This is one of the DSO I targeted. IC2948 in Ha 20x5min with the QHY8 on an Orion ED80+ WO Type IV field flattener. Guided with PHD/QHY5 on G11. Bit noisy still. Warmish night and you always need more data
. The ED80 with this FF will be good on the field in dark sites to do RGB mosaics. Doesn't catch enough light in narrowband from home. I use the hyperstar for this.
There's a full frame uncropped
here showing the full extent of the corrected field. Thanks for looking.
